The Sympathetic Powder.
Take a convenient quantity of good common Vitriol, (the Roman is best, the German may be also us'd, but that of Cyprus is not at all fit for this purpose) put it in a flat-bottom'd Earthen Pan, and expose it in the open Air to the hottest Rays of the Sun, removing it always at Night, and in moist Weather, till the Vitriol be Cal∣cin'd and reduc'd to a white Calx. In the mean time you must stir it every Day with a Wooden-slice, for it must never be touch'd with Iron, which is apt to weaken it, and deprive it of its Virtue, especially when the Sun has open'd its Body, and begun the Calcination, the time of which is uncertain. As soon as you perceive, that it has acquir'd a perfectly white Colour, take it out of the Pan, and preserve it care∣fully in a dry place, for this is the true Powder of Sympathy. Take a Cloth stain'd with some Blood from the Wound, and strew this Powder upon it, then lay it in a temp'rate place, powd'ring it every Day; and if there be Matter in the Wound, re∣ceive some of it upon a Cloth, and strew it with the same Powder.
If the Wound require Suppuration, lay the Cloth in a moist place; if to be dry'd in a dry place; and if you are oblig'd, by reason of the depth of the Wound, to make use of Tents, put 'em in clean and dry, and strew the Powder on 'em when you take 'em out, continuing to observe the same Method, till the Wound be heal'd. I have seen the Solution of this Powder apply'd to Men with extraordinary Success for Wrenches and Sinew-strains; for many Persons have been cur'd very speedily and more effectually, than if they had us'd all other Remedies, by binding a Linnen-Cloth, five or six times doubl'd, and dipt in this Solution, about the Part, and re∣newing it twice a Day. 'Tis true, this is not the effect of Sympathy, but those who are cur'd by it are very well satisfy'd, tho' they are ignorant of the cause to which they owe their recovery; and 'tis certainly more effectual in these cases, than either the Imperial or Angelic-Water, or that of the Queen of Hungary, and even than all Balsams, Oils, and Ointments whatsoever. By the same Method you may cure
